|First appearance:||Field of Nightmares|
|Portrayed by:||Janyse Jaud|
Medelia is a teenage field hockey player from a rival school and a direct descendant of sorcerer-queen Medea, whom Cronus awakens using an ancient dragon-shaped medallion. He exploits Medea's hate towards Jay's ancestor, Jason, who scorned her shortly after she helped him steal the Golden Fleece. She leads the Amazons as a warrior herself against the heroes and drives a chariot pulled by a dragon. She can also magically transport her victims to remote locations, as well as manipulate anything with magic as long as she is wearing the pendant. After the pendant was removed, she returns to normal and had no recollection of her time as Medea. Herry, Archie, and Odie go head over heels for her, and even Jay seems to be attracted, much to the annoyance of Theresa and Atlanta. Her first and only appearance is in Field of Nightmares.
